Paragraph:
The nuclear charge is non-uniformly distributed within a nucleus of radius . The charge density [charge per unit volume] is dependent only on the radial distance from the centre of the nucleus as shown in figure. The electric field is only along the radial direction.
Question: The electric field within the nucleus is generally observed to be linearly dependent on . This implies
Question: The electric field within the nucleus is generally observed to be linearly dependent on . This implies
Options
- A
- B
- C
- D
Correct answer
C.
Step-by-step solution
In case of solid sphere of charge of uniform volume density.
E=r E \propto r
Thus, for to be linearly dependent on , volume charge density should be constant.
or correct option is (c).
